security/obfsclient: deprecate and set to expire by the end of the year

- It currently does not build and does not support modern OpenSSL API
- None of the protocols it speaks are all that useful at the present time
- All the newer protocols it could be using either have severe design-
  level issues, would require way too many external dependencies, or both
- Upstream maintainer lacks motivation, spare cycles, or funding to work
  on this sort of thing these days

Remove # $FreeBSD$ from Makefiles.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.
